It was very good. They don't actually have a GF menu, though. They told me that they cannot make the currys on the menu but that almost everything else can be made without soy sauce. The server told the chef 'gluten free' when giving the order for my meal. It is all made in the same equipment, I suspect.
We've eaten three times at "Wanta Thai Cuisine," a relatively new Thai restaurant in Redmond (Overlake area), and have had exceptionally good vegetarian food like sizzling tofu, emerald fried rice and yellow fried rice.
